Review on 🚴 CYCLESPEED Waterproof Bike Speedometer USB Rechargeable - 21-in-1 Wireless Bike Computer with Backlight, Auto On/Off Odometer - Mini Bicycle Speedometer with 5 Language Options by Julian Banks

First, this cycle computer is very difficult to install (assemble) because the instructions are a joke. Also, the product description is misleading. I thought it was a USB charger but the tire gauge uses a CR2032 calculator/clock lithium battery. While the steering wheel computer can be charged via USB, the tire sensor also requires a dedicated CR2032 battery. The instruction manual is completely useless. Luckily I have a great bike shop nearby and they managed to get it working, but the pros were equally disappointed. For now it's installed and working, but I can't estimate for how long? I charged it to 100% prior to installation but I know the charge will run out quickly as it's cold in my shed. The computer itself is pretty good, which is probably the only reason I gave it two stars. Again, the bike shop was impressed by the wide range of parameters this computer measures, including rider weight and ambient temperature. FINAL ANALYSIS: I do not recommend this bike computer for beginners or beginners, it is more suitable for experienced bikers. It's too difficult to install and the performance requirements are deceiving. It requires batteries.
